As for your other question, considering Naruto: Ultimate Ninja Storm 2's popularity and success last year, it's probably the former. But perhaps the fans aren't completely "to blame", I say it was Spike that went a little overboard with the QTEs.
That's why I think it's not (only) the QTEs that are bad (or not completely to blame), but it's more like the shallowness of the gameplay that is bad. If you take away the QTEs, I don't think you can make it much more basic.
Of course, you could argue that the chains and finisher you do, can be considered QTEs. I personally don't, because I think a part of QTEs is that failing means negative consequences and willingly not doing the chains or finisher does not really put you in a disadvantage and is not even necessarily stupid because the opponent can teleport out of chains and sometimes it's best to avoid that.
If this doesn't make much sense to you, that's okay, because I frankly didn't put much thought in it.
I don't like it much either. I guess it's their way of stopping ki blast spammers.What about the Attack Clash that occurs when you hit the opponent enough with Ki-blasts, don't you think that is a little awkward?
Sorry if I make myself look a little silly.
I still don't get the whole "you watch the game instead of play it" a good amount of the fights I play involve me spamming ki blasts which do sufficient damage, the only time that I actually use clashes is when I play my Heavy-Type.
